Finley's 14-foot jumper less than two minutes into the second half put the Mavericks ahead 50-49. It also ignited the 12-2 spurt that put Dallas in the lead to stay.

Dirk Nowitzki had 26 points, and Antoine Walker had 22 points and 11 rebounds for the Mavericks, who have won all six home games this season.

The Spurs trailed by as many as 16 in the fourth quarter before an 11-2 spurt, getting to within 88-82 on Manu Ginobili's 3-pointer with 2:46 left. By the time Tim Duncan drove through the lane virtually untouched for a dunk, it was 92-90 with 18 seconds left.

But the Spurs failed to get closer. Tony Parker and Duncan missed 3-pointers in the final 10 seconds.
